2005 GMC Canyon Z71 Fleet 3.5L (6) 4-spd (4L60-E) — 1GTDT136758205824
Turn Signal Flashing At All Times

Client called, Chevy dealer has confirmed BCM has failed. BCM is obsolete through GM. Due to vin mismatch with used, is there an alternative for repairs? Used BCM and used Cluster together, does this accomplish anything? Send out for repairs?, this always seems hit or miss. Used BCM by itself and at least make driveable, possible odometer inop., other RPO's not functioning? Dive into eeprom work and use this as our guinea pig? This is simply one of many where this is an issue, his really is undriveable, it's flashing all the time, key on or off. Any and all advice will be carefully read, but maybe not acted on.

I do these via eeprom Fyi dont plug a used bcm or cluster into the vehicle or you can corrupt the mileage data in multiple components

In addition to the other suggestion, call the AC Delco TDS help line. They may be able to provide a location for one. I often find these obsolete pieces with the help of a good dealer parts counter person.

Cloning a used BCM is probably the quickest option! Would need to use a eeprom tool Or send both modules out!

If you find a donor car with the same options and engine etc…..you can swap all the computers from that car to the other so all the VINs match each other on the network. Seen that done on a water logged Cadillac DTS that likely had 30+ computers. There are cottage industries on the web that claim they can reset GM air bag SDMs. They claim they can clear the EEPROM and VIN and the crash data…

I asked my ACDelco distributor to check their locator and they found one at Merle's Automotive Supply in Tucson Arizona. You can try calling them directly or have your ACDelco distributor contact them.

Eric. If that BCM is part # …, it shows as still being listed in the GM Canada Electronics Parts Catalog and there is a “footnote” stating that it should be installed with shield part # …

A local programmer should be able to do this via eeprom and a used BCM with the same part #.

All helpful suggestions, GM and Ac/Delco claim it is indeed obsolete. Customer did not want the expense of cloning a used module so there it sits. There is a Dorman option but I think that is a poor option at best. It has been offered up but no response. Fortunately it is sitting at his house and not my lot. Thanks for all your help, E.

eBay has a BCM cloning service for for your particular vehicle $79.99 and free return shipping. If I remember that located in Florida I've used them twice with success. Second option bypass the turn signal portion from the BCM get a pinout and use an external flasher I did one on a equinox for a lady that was on a fixed income and on a limited budget. Best of Luck !
